BRAKE FOR ROLLER-SKATES.

Specification of Letters Patent. Patented J an. 31, 191 1 Application filed July 26, 1910. Serial No. 578,911.

To all whom it my concm:

hging had to the accompanyin Be it known that I, SAMUEL J. Nnsnrr'r, Sr., a citizen of the United States, residin at Elizabeth, in the county of Union and tate of New Jersey, have mvented certain new and useful Improvements in Brakes for Roller-Skates; and I do hereby declare the .following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it aprtains to make and usethe same, reference drawings, and to figures of reference mar ed thereon, which form a art of this s ecification.

My new braking device or roller-skates as embodied in this invention provides for the easy and quick substitution of one covering for another, these coverings being used on the periphery of a brake-wheel to receive the friction when the brake is 0 rated. When worn out these bands are rep aced, and since the bands are cheap they make the operation of the skate inexpensive, as far as its braking attachment is concerned, and always provide a good surface for frictional contact' to stop the skate when it is desired to cause the brake to act.

Theinvention is particularly adapted for those skates where a brake-wheel is used against a surface or strip attached to the skate body or any other convenient element, and is usedwhen the skate is tilted at a certain angle so that the brake-wheel is forced to bear on theground and on the skate and to be locked against rotation by this contact and-thus act to stop the skate.

.The invention has a further object of providing a brake-wheel-with means for pro-- venting the transverse movement of the strip onits peri' hery and thus insure the strip and the bra e-wheel being alined so that the I stri will not ride ofi' sidewise.

1 brake for roller-skates- I panying drawing, in whiche inventionv is used on a device of thev 1 class illustrated and described in myPatent No." 989,53,6, issued November 9, 1909, for a The invention; is illustrated [in the accom- .F1gure11 .a side view of the rear of a skate. Fig. 2 is faplan view 'showingthe faxleof'the'skate with the brakingattachment arranged thereon. Fig. 8 is a 'Zi'vi'ew 'Iof-thebrake-wheel, rand Fig. 4 ma The brake-wheel is adapted to be used on any kind of roller-skate and is preferably mounted so as to be used at the rear of the skate and in a position where it will be thrown into operative-engagement when the skate is tilted backward on the back wheels of the skate, thus acting to stop the skate when the foot is tilted backward at the will is ayoke 14 which is U-shaped and arranged to swing, near. its closed end, on the axle 12. On the projecting end of the yoke is the brake-wheel 15 mounted on an axle 16 which in turn is passed through the projectin ends 17 of the U-shaped yo e 14. The wheel is limited in its do nward pull on the yoke by the engagement of the yoke, at the point 18, with the bracket 11 or with any other element suitably dispose Secured to the skate 10, preferably by being clam ed under an end of the bracket 11, is a bra ing-stri 19 which extends down 15 with a peri hera annular groove 20, and on the skate w eel I put a band 21 which 18 formed of material, or provided with a surface of material, that makes good frictional contact with the braking-strip 19, or with the element which it en ges. I show but one annular groove 20 m the illustration,

rake- ,between the brac et 11 and the brake-wheel but it will be understood that it can 'be duplicated'or a series 10f these grooves put in place. I prefer, however, to leave. the maor' portion of the peri holy of the brake: wheel flat, as at 22, 80 t at more surface for braking is-provided without havin a number of raised portions or ridges w erethe wear-would be centered and which would not bedesirable because the frictional surface would be reduced. The hand 21 mally hold the brake-wheel from engage made, if desired, of elastic material, such as a band of rubber, and can be placed over the brake-wheel 15, being normally of slightly smaller diameter, and it would thus be forced, by its own elasticity, into the groove 20, as shown in Fig. 2, thus providing considerable space 23 for braking surface, and causing the portion 24 to grasp the groove 20 and prevent transverse or side motion of the brake-band 21011 the brakewheel 15. The brake-band 21 is adapted to take the wear from the brake-wheel 15 and it can be easily replaced, when worn, by simply removing the split key 25 which holds the axle 16 in place, and then removing the brake-band and replacing it by a new one.

Having thus described my invention, what I claim'is:

1. A braking device for roller-skates comprising a U-shaped yoke adapted to swing on the axle of a roller-skate, a brake-wheel on the end of the swinging yoke, means for limiting-the swinging of the yoke to norment with the surface on which the skate travels, the brake-wheel being adapted to be forced. in engagement with the ground andwith the skate when the skate is tilted,

. the brake-wheel having an annular peripheral groove therein, and a brake-band arranged on the periphery of the brake-wheel and having a degree of elasticity-sufiicient to cause the-portion of the brake-band surrounding the groove to fit in the groove to prevent transverse motion of the band on the brake-wheel,

2. A brake-wheel for roller-skates having an annular groove in its periphery, and an elastic brake-band on the periphery of the brake-wheel and adapted to enter the groove oaasae by its own elasticity to prevent transverse movement of the brake-band.

3. A brake-wheel for roller-skates, and a band arranged on the periphery of the 'movement of the brake-band on the brakewheel. Y

4. A brake-wheel for roller-skates having the major portion of its periphery flat and having a central, annular groove arranged around its periphery, and a rubber band of slightly smaller'diameter than the wheel in a place thereon and held by its own tension so that a portion of its surface will be drawn into the groove to prevent transverse movement of the brake-band on the brake-wheel.

5. A brake-wheel for roller-skates having the major portion of its periphery flat and having a central, annular groove arranged around its periphery, and an elastic band of slightly smaller diameter than the wheel in place thereon and held by its own tension 7 so that a portion of its surface will be drawn into the'groove to prevent transverse movement of the brake-band on the brake-wheel. In testimony that I claim the foregoing,

' I have hereunto set my hand this 25th day of July 1910.
